Description of problem: When graphical installation starts the X server, it uses vertical refresh rates beyond the flat panel capabilities, at least with ViewSonic VP171b-2. The flat panels generally top out below 85 Hz, and the X server is started at vertical freq above 85 Hz. Therefore, only text mode installation is possible with flat panels. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
linux resolution=1280x1024 worked with my flat panel now. That should not be necessary.
Unfortunately, we generally can't probe a lot of useful information in a generic fashion for LCDs. What's the output of ddcprobe?
The monitor displays frequences as 'Out Of Range, H.Frequency: 54 kHz, V.Frequency 86.6 Hz'. Sometimes it goes to 86.9 Hz. I am using DVI.

I had the same problem installing FC5 on an Acer Travelmate 4100.
Looks like we need to use Option "DDCMode" "on", but only in some cases. Investigating when to do that and when not.
This should be better in the next build.
